/**
 * A factory interface for creating {@link MetastoreProperties} instances based on user-defined properties.
 * <p>
 * In general, the metastore type of a catalog follows a two-level structure:
 * - The first-level type is determined by the catalog type (e.g., "hive", "iceberg").
 * - The second-level type is a subtype that needs to be registered individually (e.g., "hms", "glue", "dlf").
 * <p>
 * Each catalog type should have its own implementation of this factory interface,
 * with its supported subtypes registered internally.
